Randomized Controlled Trial
Acupuncture analgesia for temporal summation of experimental pain: a randomised controlled study.
Temporal summation of pain, a phenomenon of the central nervous system (CNS), represents enhanced painful sensation or reduced pain threshold upon repeated stimulation. This pain model has been used to evaluate the analgesic effect of various medications on the CNS. ⋯ EA induces bilateral, segmentally distributed and prolong analgesia on both SPT and TST, indicating a non-centrally specific effect. This effect needs to be verified with heat or mechanical model and in pain patients.

Randomized Controlled Trial
Effects of pain management on sleep in preterm infants.
This study was conducted to gain better understanding of the prolonged effects of pain and pain management on preterm infants' sleep. ⋯ Pain management with oxycodone markedly altered the structure of the subsequent sleep period. This reduced amount of REM sleep may have consequences for brain development in preterm infants.
